LAMP SHADE.

applmmon and .imaary 21, 1925. serial no. 3,755.

This invention relates to lamp shades and more particularly to shadesconstructed of silk, parchment or the like, stretched u on a wire'frameto give the same leasing form and dimensions. Shades of is character areusually round or oval and oftentimes tapered from the' top toward thebottom.

It is the object of this invention to provide suitable means forassociating photographic transparencies with these sha-des which will atthe same time maintain the transparency in a vcurve corresponding to thecurve of that portion of the lamp shade.

A further obiect of the invention is to provide a translucent lightdiffusing member which is e ual in size to the transparency and isplaced eneath said transparency and the source of light over which theshade is adapted to `be placed.

With these broad general objects in view, the invention will now bedescribed by reference to the accompanying drawing in which,

Figure 1 is a perspective view of a lamp shade embodying this invention.

Fig. 2 is a vertical-cross section of a portion of the lamp shade andtaken through the photographic transparency online II-II of Figure 1.

Fi 3 is a modified form of the way in whic the photographic transparencymay be applied to a lamp shade.

Fig. 4 is a stretch-out perspective view of the several parts of thisinvention and showing the lamp shade in a fragmentary way.

Fig. 5 shows a modied form of a transparency which may be applied to thelamp shade. p

Fig. 6 is an enlarged detailed section of ythe frame inter-clampingmeans.

Fig. 7 is a face view of the same showing the way the spur shaped clampsma be prssed from one of same frame mem rs, an

y Fig. 8 is a horizontal section of the plotogra hic transparenc takenon line II II of Fig. 5 and7 showing in particular the way all membersconform to the general curvature of the lamp shade.` With reference atthis time to the drawings in detail wherein similar reference charactersrefer to like parts throughout the several views/and wherein 9 is theordinary lamp equipped with the well known shade which 1s constructed byutilizing a wire frame 10 which is covered with any desired lwillpresent a completely black su material lsuch as parchment, silk or othercloth 11.

This shade need not be especially conj structed .for use with thephotographic transparencies forming al part of this invention, ut may bestretched with any degree of curvature over frame 10. These photographictransparencies are preferably made upon a pliable material 12 which isslightly larger in size than the opening 13, out into material 1,1 whenthe transparencies are being applied to the shade. A translucent pliablesheet 14 is preferably, though not necessarily, placed in juxtapositionwith trans- `parency 12 and between said transparency and theilluminating means of the light not here shown,

Numerous ways of securing transparencles 12 and sheet 14 may bedevised'for securing the same over opening 13. These transparencies andopenings may also be made .in any desired4 shape and the same placed inany position or location over the surface of the lamp shade walls. Forthe purpose of illustration, the preferable Way o mountingtransparencies 12 and sheet 14 is shown to be a frame of metal or someother suitable material made up of a front fra-me 15 and a rear frame16. The openings in frames 15 and 16 are slightly smaller'than theopening 13 in shade'11 and slightly larger than the outside dimension oftransparency 12 and sheet 14. Rear frame 16 may or may not be ofi-set asshown in the drawings, and the method of securing the two together maybe varied. This method is shown here to be a series of s urs 18 stampedout of front frame 15 and) adapted to pass rearwardly through materiall11 and thence through openings 19 registering therewith and formed inrear frame 16. This structure binds material 11 around the edges ofopening 13 and precludes any fraying, tearing or running' of the fabric.As shown in Fig. 3, the transparency and translucent sheet 14 may beglued directly together with fabric 11 between the same. To remove theunfinished appearance when this method is em loyed, any suitable bindingsuch as a metal ic frame or metallic lace 20, may besecured around theouter edges of transpar-,

ency 12 as shown.

It is a recognized fact that tralparencies ace when no light is lacedehnd them.l If this feature 1s un esirable, the shade may be constructedwith a covering of voile 21 stretched over the transparency and frameonly, or may be bound to the frame as is the material 11 to form acomplete outer covering over the entire shade which conceals toga lar eextent the transparencies when the light 1s not lit.

As is shown in Fig. 8, the Jframes are formed to conform to thecurvature of that particular portion of the shade to which thetransparency is to bey applied. The transparency being pliable, will beheld securely with its tace conforming to the curvature of said shade.

It is understood that lnany changes and modifications may be made inthis invention, and it is desired not to be limited in its constructionexcept as deiined in the appended claims.

What I claim is:

l. In a lamp shade of the class described,

having walls oi cloth or the like. said walls having'openings cuttherein, photographic v transparencies positioned over said openings,

a translucent sheet of a size equal to said transparencies injuxtaposition thereto and common means for holding said transparenciesand translucent sheets over said openings and conforming the same to thegeneral contour of said shade cpinprising a front and a rear .frameadapted to interlock and engage said cloth walls therebetween.

2. In a lamp shade oi3 the class described, having a frame, cloth or thelike stretched vover said frame to iorm walls, said walls being providedwith openings, said openings each having a photographic transparencythereover, a translucent sheet behind said transparency, and an innerand an outer frame conforming to the shape of said vopening adapted toretain said transparency and said translucent sheet therebetween inposition and in a position conforming to the general contour of saidshade.

3. In a lamp shade of the class described,

, .having a frame, cloth or the like stretched over said frame to formwalls. said walls being provided with openings, said openings having aphotographic transparency registering therewith, and an inner and anouter frame for retaining said transparency in the registered position,both of said frames being curved to correspond to the general curvatureof said shade at said opening whereby the said transparency is held in acurved position corresponding 'to said shade.

4. In a lamp shade of the class described, having a frame, cloth or thelike stretched over said frame to form walls, said Walls being providedwith openings, a pliable photographic transparency registering with eachof said openings, and means for retaining said transparency in theregistered position comprising a pair of frames, means integral with oneof said frames for piercing said cloth and engaging the other of saidframes, wherebyA said transparency is given a curvature correspondingtosaid shade, and said cloth or the like is retained in its normal.position around said transparency.

5. In a lamp shade of the class described, having a frame, cloth or thelike stretched over said frame to form walls, said walls being providedwith openings, a pliable photographic transparency registering with eachof said openings, and means including a pair of registering metallicframes for holding said transparency in place, said fra-mes having acurvature corresponding to the curvature of said shade at said openingfor maintaining the transparency in the same degree of curvature as saidshade.

6. In a lamp shade of the class described, having a frame, cloth or thelike stretched over said trame to form walls, said walls being providedwith openings, a pliable photographic transparency registering with eachof said openings, and means 'for securing said transparency to saidwalls, said means being adapted to protect the material in said wallsfrom iraying or running at the edges formed by the cutting of saidopening.

7. In a lamp shade ofthe class described, having a frame, cloth or thelike stretched over said frame to form walls, said walls being providedwith openings, a pliable photographic transparency registering with eachof said openings, a frame supporting said transparency and gripping saidwalls at the edge of said opening and an outer covering forming a partof said lamp shade stretched over said transparencies whereby the sameare concealed when said lamp shade is not illuminated from the innerside.

In .testimony whereof I h'ereunto at'ix my signature this 17th daqy ofJanuary, 1925.
